With help from Matt Daimler, founder of SeatGuru, a website designed to help passengers find comfortable airplane seats, and Randy Petersen, creator of the Frequent Flyer Network, which includes the SeatExpert guide to airplane seating, here are some pros and cons of flying the cheap seats onboard three domestic and four international airlines. One of the keys, experts say, is seat pitch, which SeatGuru defines as: "the distance from any point on one seat to the exact same point on the seat in front or behind it." Generally, the greater the seat pitch, the greater the legroom.

Pros: Leather 19.7-inch-wide seats. Headrests have wings, tilt and can be adjusted for height; colored mood lighting includes dawn, dusk, daylight and sleep modes; each seat has a power outlet for a laptop, iPod, etc., that doesn't interfere with foot space; in-flight entertainment system offers on-demand food and entertainment (free and paid options).

Cons: Less legroom; many entertainment options are fee based.

Hawaiian Airlines — New Airbus 330-200s

Seat pitch: 32 inches

Pros: Seats are 18.2 inches wide; headrest is adjustable in six directions and has a USB port for charging or playing a portable device; each seat has in-flight entertainment.

Cons: An additional inch of seat pitch and a laptop power outlet would be even better.

Pros: New planes and the 747s Lufthansa is refurbishing have seats designed to increase personal space and lumbar support. Each seat has in-flight entertainment.

Cons: Width of seats at 17.5 inches is less generous than others.

Qantas — Airbus A380

Seat pitch: 31 inches

Pros: The 18.1-inch seat base moves in conjunction with recline; seats have a flexible foot net that holds your feet like a footrest. An adjustable headrest and cushioned armrests are designed for side-sleep.

Cons: Seat pitch is comparatively snug.

Air New Zealand — Boeing 777-300ER (regular service begins on April 1)

Seat pitch: 33 inches

Pros: Headrest has a slip-on pillow; 17.1-inch seats have six inches of recline and footnets. New: the Economy Skycouch. Buy the middle seat and it converts to a soft surface.
